You can put this solution on YOUR website!
I assume your expression was
\n" ); document.write( "\"2%2Alog%283%2C%28x%2B3%29%29-5%2Alog+%283%2C%282x-1%29%29%2Blog%283%2C5%29\" where each \"3\" was the base of a logarithm.
\n" ); document.write( "You must have learned properties of logarithms such as
\n" ); document.write( "\"log%28b%2C%28a%5Em%29%29=m%2Alog%28b%2C%28a%29%29\"
\n" ); document.write( "\"log%28b%2C%28a%2Ac%29%29=log%28b%2C%28a%29%29%2Blog%28b%2C%28c%29%29\"
\n" ); document.write( "\"log%28b%2C%28a%2Fc%29%29=log%28b%2C%28a%29%29-log%28b%2C%28c%29%29\"
\n" ); document.write( "You can read those properties from right to left, too, because the equal sign is a two-way street.
\n" ); document.write( "So \"2%2Alog%283%2C%28x%2B3%29%29=log%283%2C%28x%2B3%29%5E2%29\", and you can apply all of those properties to transform your expression, like this:
\n" ); document.write( " \n" ); document.write( "
\n" );
